  1. 1. Governance structures for promoting renewable energy sources

    Författare :Ole Langniss; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; regulation; transaction cost economics; renewable energy;

    Sammanfattning : This study seeks to find answers to the question of how much competition is introduced by different types of regulation aimed at promoting electricity generated with renewable energies. For this purpose the partial equilibrium model is applied. LÄS MER

  3. 2. Land Use Conflicts between Agriculture and Energy Production : Systems Approaches to Allocate Potentials for Bioenergy and Agrophotovoltaics

    Författare :Daniel Ketzer; Peter Schlyter; Henrik Ny; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renewable energies; Geographic Information Systems; Agrophotovoltaics; Participatory technology development; Responsible Research and Innovation; Physical Geography; naturgeografi;

    Sammanfattning : The developments towards a bio-based economy and a renewable energy-based power supply require thorough assessments of feedstocks and frameworks. In the past, political targets for increasing shares of renewable energies for combatting climate change have triggered direct land use changes (LUCs) and even indirect land use changes (iLUCs).

  4. 3. Methanation of biosyngas in a fluidized bed reactor

    Författare :Martin Seemann; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENERGY TECHNOLOGY; REGENERATIVE ENERGIES; GASIFICATION OF WOOD; FLUIDIZED BED PROCESSES; CHEMICAL ENGINEERING; FUEL TECHNOLOGY; ALTERNATIVE ENERGIES; METHANATION OF HYDROGEN-CARBONMONOXIDE MIXTURES; SYNTHETIC FUELS; NATURAL GAS; BIOGASES;

    Sammanfattning : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. LÄS MER
